UNITED STATES ALVIN J. IVIUSSELMAN, OF CHICAGO, ILLINOIS.

GOLF-BALL STRUCTURE AND METHOD OF MAKING SAME.

Application filed February 25, 1920.

To all whom it may concern Be it known that I, ALVIN J. MUssELMAN, a citizen of the United States, residing at 804 Washington Blvd, Chicago, in the county of Cook and State of Illinois, have invented a new and useful improvement in Golf-Ball Structures and Methods of Making Same, of which the following is a specification.

This invention relates to golf ball struc tures and to the process of making same.

It is an object of this invention to provide golf balls having greater resiliency and which will consequently have greater carrying power.

This and other objects are accomplished by my process which consists primarily in applying a dry lubricant such as graphite to therubber as the ball is wound and which is fully described in the following specification and illustrated in the accompanying drawings in which Figure 1 is a perspective View of a golf ball showing diagrammatically one method of applying the dry lubricant to the rubber band, and Fig. 2 is a modified form of the process.

As shown in Fig. 1, the golf ball 10 is turned in the direction of the arrow in any desired manner so as to wind up on the strand of rubber 11, which, however, is kept stretched as it is fed from a spool (not shown). The strand 11 passes over a block of dry lubricant as graphite or mica l2 and someof this sticks to the under side oi the strand and remains permanently held between this strand and the layers upon which it is wound. Any desired form of center and cover may be used.

When therefore this ball is struck, the strands of rubber forming the ball do not cling tightly together as is the case in the ordinary golf ball, but each strand being lubricated moves slightly during the instant of deformation and then instantly tends tr. return to its normal position. The resul; is that it is more lively and resilient than in the unyielding forms which act more nearly like a solid rubber ball.

In Fig. 2 I have shown a ball 10 in the process of winding on a strand 11 The Specification of Letters latent.

Serial No. 361,283.

dry lubricant is sprayed on by means of air pressure through the tube 13. it is intended primarily to fall on the under side of the oncoming strand, but some will also fall on the outside strands of the ball.

Either of these methods may be employed to all of the wound strands of the ball or to selected portions only.

The two methods shown are illustrative only and while I have shown and described but two embodiments of my invention it is to be understood that it is capable of many more modifications. Changes there fore in the construction and arrangement may be made which do not depart from the scope of the appended claims in which it is my intention to claim all novelty inherent in my invention as broadly as possible in View of the prior art.

V'Vhat I claim as new and desire to secure by Letters Patent is:

1. The process of making golf ball structures consisting in winding a portion of said structure with a strand of rubber under tension and applying a dry lubricant between the strands.

2. The process of making golf ball structures consisting in winding a portion of said structure with a strand of rubber under tension and applying: a dry lubricant to the strand just before it reaches the partially wound ball.

3. The process of making golf ball structures consisting in winding a portion of said structure with a strand of rubber under tension and applying a dry lubricant to the underside of the strand just before it reaches the partially wound ball.

4:. The process of making golf ball struc tures consisting in winding a portion of said structure with a strand of rubber under tension and forcing a block of dry lubricant against one side of said strand as it is being wound thereon.

5. A golf ball structure having a body consisting partially of a wound stretched rubber strand and a lubricant between the layers formed by said strand.
